First-half goals from Oscar and Frank Lampard ensured it was an unsuccessful first game back in the top flight for Steve Bruce's players.

The Blues could have been in front within six minutes, but Lampard saw his spot-kick stopped superbly by debutant Allan McGregor.

Hull, who improved after a disappointing first 45 minutes, failed to turn decent territorial possession into significant attempts on Petr Cech's goal.

Chelsea begun the game in blistering style and were awarded a penalty after McGregor darted off his goal-line to bundle over Fernando Torres.

However Lampard saw his well hit penalty palmed away by McGregor, who redeemed himself after his careless mistake.

The home side were soon in front thanks to great interplay between Eden Hazard and debutant Kevin De Bruyne, who released Brazilian international Oscar to poke the ball under McGregor and into the net.

Lampard nearly double Chelsea's lead only a minute later, but the Scottish number one was equal to his attempt tipping the ball over the crossbar.

But at the third attempt Chelsea's record goalscorer netted his 204th goal for the club in stunning fashion mid-way through the half.

Lampard's 30-yard free-kick gave McGregor no chance as the ball rocketed into the top corner of the net.

The England international continued his personal battle with the Hull goalkeeper right on half-time as he saw his fierce attempt turned around the post.

From the resulting corner Branislav Ivanovic's header was stopped on the line by McGregor clearly enough that goal-line technology was not needed to be used for the first time.

After the break Hull enjoyed much more of the possession as Mourinho's side relaxed some what.

Robert Koren's long range effort and Curtis Davies header were the closest the Tigers came to getting on the scoresheet.

In a second-half not full of chances, substitute Andre Schurrle nearly registered a third for Chelsea but his delicate chip just sailed over the bar.

However it did not matter as Mourinho secured victory at the first time of asking since returning to the club.
